Improvement in the mode of



UNITED STATES PATENT QFFICE.

HENRY VANDER WEYDE, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 121,475, dated December5, 1871.

To all whom it may concern:

Be it known that I, HENRY VANDER WEYDE, of the city, county, and Stateof New York, have invented a new and Improved Method for Applying Coloror Tints to the Surface of Photographs or other surfaces, of which thefollowing is a specification:

The purpose of my invention is two-fold. First, to produce by a rapidand easy process st-ippled tints of any shade or color over theback-grounds and other parts of photographs, albumenized, and othersurfaces, which will have the appear ance of having been produced at theexpense of a vast amount of labor and artistic skill. These stippledtints have thus far only been successfully produced by good artistsafter years of practice, using a fine brush charged with wet color, anddotting one stipple or stroke at a time. Second, to fix dry colors ortints on albumenized or other surfaces. Dry colors or tints have neverbefore been fixed or even applied to albumenized or glossy surfaces.

My method consists of rubbing, with the aid of a soft pad, dry colors ortints in any form, and fine pulverized pumice-stone or its equivalent,using them together or separate on the albumenized or other surfaceuntil it adheres by penetrating into the grain of the same. In this wayI secure in an incredibly short time all the advanta ges of thecustomary method, While the result obtained is even superior in artisticappearance and atmospheric effect to the most laborious andhighly-finished productions.

My method must not be confounded with any old methods of applying drycolor or tints to surfaces, as they are all superficially applied, havea dead, opaque, flat, chalky effect, and can be readily blown or rubbedofi' while they will not even temporarily adhere to albumenizedsurfaces, while according to my method dry tints can be applied to anysurface, cannot be rubbed or blown off by ordinary means, and the effectis atmosphericallytransparent, and looks b y no means opaque or chalky,but like the laborious artistic manipulation of a fine wet brush.

I claim The use of pulverized pumice-stone, emery, or its equivalent,for the purpose substantially as described.

HENRY VANDER WEYDE.
